The SEC and SROs

Imagine a sprawling, high-speed rail network carrying trillions of dollars in cargo every single day. If every conductor decided their own speed limit and every switch operator ignored the signals, the system would collapse into catastrophic wrecks. The United States financial markets represent the most complex and heavily trafficked economic engine in human history, and they function only because of a carefully engineered system of regulatory oversight. At the pinnacle of this system sits the federal government, establishing the ultimate rules of the track. Yet, managing the intricate day-to-day operations of every specialized train requires delegating authority to those actually working on the rails. Understanding this division of labor—between the ultimate federal authority and the industry’s self-policing bodies—is the foundation of your career in the securities industry.
